I strapped a Saturn V to one of my ummus, and for some reason he nose dived into the dirt, fired a unsuited ummu out of the harp gun and he turned into a lumpy rock, strapped a JATO to a ummu and he spun around doing inverted loops, i guess the G's would've ripped his body to pieces, there's also when i ruined the gear on the xr-2 and was then unable to open the nosecone and the doors so they died from hypoxia.
The best one was when i summoned a second Venus some how and it landed on top of one of my guys.
